I completed my M.S. (Animal Behavior and Physiology) in the summer of 2009. My thesis work focused on a federally endangered desert rodent, the giant kangaroo rat Dipodomys ingens. My study involved the social structure of their communities at varying population densities and associated male and female behaviors including dispersal and reproductive strategies and patterns of space use. I used nine microsatellite DNA markers to genotype and investigate relationships among ~200 individuals at my study site in the Carrizo Plain National Monument. Radio tracking telemetry data collected on 24 males (of reproductive age) over a period of a month during the breeding season in 2006 allowed insights into male activity patterns during a year of peak population density.
